They have the same 0-60 time of 6.7 seconds.
The Acura does not have a supercharger, but has the same power as the Cobalt supercharged. Not having a supercharger makes the insurance lower.
On the other hand, Acura is a luxury sports brand and they are more expensive to buy, maintain, and fix. And Insure.
So I would say the insurance is the same.
The Acura is more reliable and has better quality, but the Cobalt interior looks like it has better quality and looks more expensive.
I would say the Acura handles better because it is lighter and slightly smaller. I have driven the Type S Acura RSX. It was fun to drive. The Acura also has better potential. Honda/Acura engines have lots of potential for power.
I would say the Acura is a much better car, but it is also more common. You might want something different then what everyone has.
